Ifomula yokubala yokufudumeza isithando somlilo

Ifomula yokubala i-inductance ye-coil-core coil: I = (0.01 * D * N * N) / (I / D + 0.44)

phi:

(1) I-Coil inductance I, iyunithi: i-microhenry;

(2) Ikhoyili ubukhulu D, iyunithi: cm;

(3) Inani lekhoyili lijika N, iyunithi: ukujika;

(4) Ubude bekhoyili I, iyunithi: cm;

Ngokutsho kwefomula, i-inductance I ilingana nenani lokujika N yekhoyili.

I-inductance I imele iimpawu zendalo zekhoyili ngokwayo kwaye ayinanto yakwenza nobukhulu bangoku. Ngaphandle kweekhoyili ezikhethekileyo ze-inductance (i-color code inductance), i-inductance ngokuqhelekileyo ayiphawulwanga ngokuthe ngqo kwikhoyili, kodwa iphawulwe ngegama elithile. Ubungakanani be-inductor inductance ikakhulu buxhomekeke kwinani lokujika (inani lokujika) kwekhoyili, indlela yokucima, ubukho okanye ukungabikho kwe-core magnetic kunye nezinto eziphathekayo ze-magnetic core, njalo njalo.

Ngokuqhelekileyo, i-coil ijika kwaye i-denser iikhoyili, i-inductance inkulu. I-coil ene-core magnetic ine-inductance enkulu kune-coil ngaphandle kwe-core magnetic; Okukhona ukungeneka kondoqo wemagnethi, kokukhona i-inductance inkulu.

Iyunithi eyisiseko ye-inductance nguHenry (uHenry ngokufutshane), emelwe yileta “H”. Iiyunithi ezisetyenziswa ngokuqhelekileyo ziyi-millihenry (mH) kunye ne-microhenry (μH). Ubudlelwane phakathi kwabo bu: 1H = 1000mH; 1mH=1000μH.
